Your cousin has $90 to spend on video games and movies. The equation 30x+15y=90 represents this situation, where x is the number of video games purchased and y is the number of movies purchased. Graph the equation.

9514 1404 393

  see attached

Step-by-step explanation:

The intercepts can be found by setting one variable to zero and solving for the other.

y-intercept: 30·0 +15y = 90  ⇒  y = 90/15 = 6, point (0, 6)

x-intercept: 30x +15·0 = 90  ⇒  x = 90/30 = 3, point (3, 0)

The graph is easily made by plotting the intercepts and drawing a line through them.

I like to let a graphing calculator do the graphing.

step-by-step explanation:

1. the cylinder is a. 54

2.   a.108 /

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer
